Electrical Connections

Connection by a qualified electrician is recommended.

All furnaces in the range are single-phase and operate over the voltage ranges 100 to
110 volts or 200 - 240 volts. Check the rating label before connection, see "Warning
Labels" 
for location of rating label. To check that the OP.Hi setting is correct for the
appropriate voltage, or to change to another setting, follow the instructions in section
0.1.

The electrical supply should be fused at the next standard size equal to or higher than
the design current. Where a supply cable is supplied there are internal supply fuses, in
which case customer fusing is preferred but not essential. See section 9.0 for furnace
rating power, current and fusing information.

The external connection should be either a permanent connection to a fused isolator
supply or to a socket on a fused isolator supply; the isolating switch must operate on
both conductors. Make sure that the isolator switch is within easy reach of the furnace
operator.
